Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed September 24,1906. Serial No. 335,943.

To all whom it may concern:

Be it known that we, GUsrAr HAesraoM and EMANUEL HAGs'rnoM, citizens of the United. States, residiiig at Lindsborg, in the county of McPherson and State of Kansas, have invented certain new .and useiul Improvements in Patches for Pneumatic Tires; and we do declare the following,r to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

Our invention is an improved patch `for repairing pneumatic tires, such as are used on the wheels of automobiles and other vehicles, and it consists in the construction, and arrangement of devices hereinafter described and claimed.

The object of our invention is to provide' an improved patch for use between the inner and outer tubes of pneumatic tires' for? re airing blow-outs and for use in cases in W 'ch the outer tube or casing has become broken or injured.

In the accompanying drawings, Figure 1 is a transverse sectional view of a pneu; matic tire provided with our improved patch Fig. 2 is a perspective view of the patch7 .showing the saine extended; Fig. 3 is a transverse sectional view of another form of pneumatic tire providedwith a modified form of our improved etch; and Fig. 4 isa perspective view oi'such modified i'orm oi' patch;

Our improved patch is a band of leather, rawhide, or other suitable `tough and iiexible materialj to be passed around the inner tube of the tire, between said inner tube and the outer tube creasing, and clips secured to such band, at or near the ends thereof, to secure the patch iirrnly to the side ilanges of the outer tube or casing.

Referring particularly to the -forni of our invention shown in Figs. l and 2, the band or patch 'l is of oblong rectangular foi-1n, of suitable length and breadth, and is provided at its ends with clips 2. The said clips are made oi suitable sheet metal, are V-sha ed in transverse section and have their )ottoni or outer webs $5 curved longitudinally to correspond with the radius of the tire and are provided at their outer edges with tongues 4, which may be bent ,sheet metal, are U,

inner webs 5 of the clips by rivets or other suitable fastening devices 6. which forms an extension of one end of the patch, is secured thereto, near saidend, by stitching, as at 8. lt may, however, be otherwise secured, and wedo not desire to limit ourselves in this particular. The said flap extendsl between the inner tube c and the metal tire d, and covers the space between the ends of the band or patch 1. The inllation of the inner tube causes the patch to `be ldrawn tightly around. the saine, and together with the pressure of the tire on the cli s, keeps the patch in place.

n the forni of our invention shown in Figs. 3 and 4, the clips 9 are made of spring raped in cross-section, and are secured to the patch 10 near the ends thereof by Ineens of' rivets or other suitable fastening devices 1l.. These oli s are engaged with the edges of the outer tu e or cil-singe and by their own resiliency retain their grip thereon, the patch being tightened 'connection with the accompanying drawings,

the construction and operation ofthe invention will be readily understood without rcquiring a more extended explanation.

Various changes in the i'orni, proportion, and the minor details of construction may be resorted to without departing from the principle or sacriiicing anfy of the advantages ,of this invention, as de ined by the appended claims.

Having thus described niy invention, what I claim as new, and desire to secure by Letters-Patent, isfl. A patch of the class described comprisingr a band to go around an inner tube having clips at its ends to engage the edges of an outer tube and provided with a ilap forrniiig,r an extension oi one end to lic between the inner tube and a wheel rim, substantially as described.

2. A patch of the class described compris- A ermee ing a band to go around an inner tube and set our hands in presence of two subscribing having clipsbat its endls to ngage thehedges of Witnesses. an outer tu e, sai c i s eing V-s a e in cross section and the oliter 'Webs thereoli having tongues to be bent around the flanges at y l J the edges of said outer tube, substantially as Vitnesses: described.
